	# The first step in every application using PDFNet is to initialize the 
	# library and set the path to common PDF resources. The library is usually 
	# initialized only once, but calling Initialize multiple times is also fine.
	PDFNet.Initialize
	
	# The location of the CAD Module
	PDFNet.AddResourceSearchPath("../../../PDFNetC/Lib/");
